COMBINED TYPEWRITING ANI) COMPUTING MACHINE.

Application filed February 12, 1921.

To all whom it may concern:

Be it known that I, HENRY RESCH, a citizen of the United States, residing in Bayonne, in the county of Hudson and State of New Jersey, have invented certain new and useful Improvements in Combined Typewriting and Computing Machines, of which the following is a'specification.

"This invention relates to combined type- 1 writing and computing machines, and is illustrated in connection with a machine of the Underwood-Hanson type.

It is the usual practice, in completing a computation, to adjust thecomputing mechanism', as to addition or subtraction, so that upon ty ing the 'resultor balance and actuating the enerailikiperator, the register or totalizer will be cleared. Such machines are provided with clearance or star-keys, which are lockedagainstfdepressiom unless the corresponding totalizer's or registers are cleared. When the clearance key is depressed, a star or "other clearance sign will typed on the worlesheefitoi'ndicate that thecorrect'res'ulthasbeen typed. Printing of a clearance "sign atthelbeginning of a computation will serve to show that the register'i's clear at that time 'Also, in such machines, provision'is ii'siially made of poly- BU chrome mechanism, whereby the color of the printing may be varied.

In carrying out-the invention, provision may be made Whereby,'.instead of printing "'a star or' otherclearance sign, the number representing the day of the month will be printed when the clearance key is depressed, and, instead of having a single clearance type and the typebar controlled by the clearance key, provision may be made of type-blocks ortype-lieads having thereon types adapted to print the numbers corre sponding to the different days of the month, the type-.heads'a'nd type-barbody to which they are to be attachedfbeing so constructed as to permit said type-heads to be readily attached tofor detached from, the type-bar body. -Each type-head for attachment to the type-bar body may have both the number indicating the day of the month and the 50 star, the character to be printed being determined bythe case-shift mechanism.

It is frequently desirable to print the clearance sign in a different color from that used in printing the numbers connected with illustration.

.gagement' with a pin or proje'etion- 5: near Serial No. 444,370.

the computation, and this condition is particularly true in case the number of the day of the month is printed as a clearance sign, for otherwise there would be danger ofre'ading the figures representing the day of the month as part of the number printed in connection with the computation. Provision may therefore'be made of means whereby, upon actuation of the clearance-sign-print ing mechanism, the bichrome mechanism, sct for another color, will be shifted to a position to enable printing of the number of the day of the month in the desired col'or Other features and advantages will hereinaftel' pp i 3. .5. In the accompanying drawings,' Figure'l is a fragmentary'fperspective view, showing my. invention 'ap'pliedgto much of a machine of the UnderwoodHaii? son type as is necessary for thep'urpose of Figure 2 perspective fjad-y tachable type head for usein, connection] with themechanismshown inFigure L Figure 3 is' a view, showing}a' type-head such as shown in Figure 2, offa'typebar body. w

In an Underwood-Hanson machineg when; the register is cleared a star'or. filfia f lieekey 1 may be depressed, but in case t-he register-. is not cleared the starkey l will' be locked against depression. Depression of, the star key 1 will actuate an arm 2 fixedon ashaft 3 to rock theflatter and thereby withdraw a latch l pls o fixed to the shaft 3-,, ut ofenthe lower end of a vlink 6 pivoted its upper end to an arm 8 fiziedionsh'a'ft g Ihe'lower'end of the link' 6 is normally urged against thev shaft, 3-b'y means of a spring-l0 connected to the link 6 at itsup- .100

The engagement of the frame 25 with pins 23. an'd 24 isflet erinined by means of a link 26 connectedat one end to frame 25 and at the other end to a frame 27 fixed on a rockshaft 28. The ,bichr0me mechanism just described is substantially the same as that disclosed in the-patent to Cook,No. 926,050,

une 22, 1909.

Provision may also be made of a signal arm,29 :carryin atits upper end two color fields side'by si e, a black color field 30 and a red color field' 31, adapted to be brought into position alternately to be. displayed through ar'ippeiiinig 32, so as to show at the 32 the setting ,of the bichrome meclianisn'if. In order that the bichrolne be controlled by the lever 14'of tli c earance-printing mechanism, provisio'n'inay be inade of an arm 33 on shaft 28, Wlllt lll may-be part of a bell-crank lever the printing .point, and in red detached from the cam 37. 1

3 1, of which arm 29 is also a part. At its free end arm 33 may be provided with a pin 36 to be actuated by a cam. 37 pivoted by suitable means, such as a screw 38, on a bracket 39 mounted on a fixed part of the machine. \Vlien said cam is it s norma'l position a dwell portion 40 thereof, substantially concentricwithscrew 38, will be in engagement with pin 36, which is held thereagainst by means of a spring 41, which may b connected at its lower end to screw 38 The cam 37 is also prodded with a lift portion 42 and another dwell portion 43,50 that when the cam is swung in clockwise direction the pin 36 will be lifted and the. bichro ne mechanismshifted, so as to enable printing in red and toca-use the red field oi the signal to be shown at the opening,32:= '1 he connection between thegcontrollifig.

In order, however, to, permit. readycon nection and disconnection .of the. link 44 and lever 14, the link isbent near-(heap Jcr edge of lug 47, so that,when thelink, is.

the link, by a downward movement, may readily be removed from the lever 14, or, by raising the link to the posit-ion'shown in Figure 4 and then turning it through ninety degrees about its axis, connection between 110 the link and lever may he efl'ected. WVhen the link has been turned as just, stated, it

may be attached to the cam 37 by means i of the screw 4.). Turning of the link will 14 will be maintained until the link is again It should be understood that filled portion 42 and the dwell portion 43 of the cam 37 are so arranged that, when the lever 14 is actuated, the birhrome mechanism will beshiftedand the pin 36 will ride'on the dwellpoi tion 43 before the clearance type has reached the printing position, .thus "in-.1 suring shifting of the .bichrome'mechanism at the proper time.

Usually star is printed to indicate elm ance, but. as hereinbefqre stated, it' may t" desirable to print, in place of tl1e.stal:,;a-.

To this 'end, detachable type-heads 49 may be provided, and, as shown in Figure 2, each of these type-heads may be provided with a starter printing in upper case and a' unmberi to 'indicate theday of the month in low eri'c'ase, tlie'charac'ter to be printed being' determined "by case-shift mechanism. not In'order that the type-heads 49 L may be'easily attachedto or detached from the type-bar 16, eacli'of the-type heads %9 is provided witha'shank 51 having thereon a ch e atled stud 52, the shank of which may'bepiessed in an opening 53 at the end ofjthe ty'pe ba1"16 'lhe shank 51 of the type head T na-y; also be provided with a slotv 54 tojreceiyethe shank of aiheaded stud 55 on t'ypePbarIG, the slot 5at fbe'ing enlarged b means ofi'a';no tch 56" in'one of its side 20, walls, s are; erriiit the shank pt the, stud stab es-famed into the slotj' Inpressing messenger the headed studj' 5' 1nto the slot,""'the wallsj of the latter jareflsprnng slightly-apart 'sd'that removal of the shank dementia-5'5" tjr iajjth' s ower be resisted.
